✅ Type: Glass Body Reed, matches the required switch type.
✅ Circuit: SPST-NO, matches the required normally-open contact configuration.
✅ Voltage - Switching DC: 200 V, which exceeds the required minimum of 24 V for the sensing circuit.
✅ Mounting Type: Through Hole, matches the required PCB mounting style.
✅ Termination Style: Axial, matches the required lead style.
✅ Operating Temperature: -40°C to 125°C, which is wider than the required -40°C to +85°C range.
✅ Application fit: This is a reed switch intended for magnetic actuation and is suitable for door open/close detection in a low-current 24 V DC sensing circuit.
All required specifications are satisfied, so this component is approved.
